Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a multi-functional positioning fixture for machining mechanical parts. Background Technology

[0002] With the development of personalized consumption trends, customers' demand for customized mechanical products is constantly increasing. This means that machining companies need to frequently switch between producing parts with different specifications and requirements. Traditional positioning fixtures are often designed only for specific workpieces or specific processing techniques, and cannot meet the rapidly changing customized production needs. Multifunctional positioning fixtures with a large clamping range can be flexibly adjusted to adapt to the clamping and positioning of various customized parts, providing companies with a more efficient production solution.

[0003] Since modular fixtures are composed of multiple modules, although they are flexible, there are inevitably gaps between the modules. When used to clamp small parts, these gaps are amplified by vibration, which makes the parts less secure and more likely to fall out of the fixture. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional positioning fixture for machining mechanical parts, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional positioning fixture for machining mechanical parts, comprising:

[0006] Clamping plate;

[0007] A clamping assembly is placed inside a clamping plate. The clamping assembly includes a transmission plate slidably connected inside the clamping plate, a clamping rod slidably connected to the transmission plate, a groove formed on the clamping rod, a sliding shaft fixedly connected to the transmission plate, the sliding shaft slidably connected to the groove on the clamping rod, a transmission rod slidably connected to the bottom of the transmission plate, a transmission block provided on the transmission rod, a universal joint fixedly connected between the transmission rod and the transmission block, a damper fixedly connected to the transmission block, a series plate slidably connected to the damper, a fixed rod fixedly connected to the series plate, a sliding frame slidably connected to the fixed rod, a circular block fixedly connected to the bottom of the clamping plate, the fixed rod slidably connected to the circular block at the bottom of the clamping plate, and the transmission rod rotatably connected to the clamping plate.

[0008] Furthermore, the sliding frame is fixedly connected to the bottom of the clamping plate, and a slot is provided on the circular block at the bottom of the clamping plate, and the fixing rod is slidably connected in the slot of the circular block.

[0009] The above technical solution is adopted: by opening a slot on the round block, it is convenient to fix the fixing rod through the slot in the round block during use, so that the connection between the fixing rod and the round block is tighter.

[0010] Furthermore, the bottom of the clamping plate is provided with an opening, and the transmission rod is rotatably connected to the bottom of the clamping plate via a rotating shaft.

[0011] The above technical solution is adopted: when the transmission plate is pressed down during use, it will drive the transmission rod to slide. By opening a hole at the bottom of the clamping plate, the transmission rod is prevented from being blocked during use.

[0012] Furthermore, a fixed shaft is fixedly connected to the transmission plate, and a fixed plate is fixedly connected to the fixed shaft, with a sliding hole provided on the clamping plate.

[0013] The above technical solution involves fixing a fixed shaft to the transmission plate. When the operator presses the fixed plate down to the appropriate position, the bolts on the fixed plate can be used to fix the plate, preventing it from sliding further and thus securing it.

[0014] Furthermore, threaded grooves are provided on both the connecting plate and the fixing rod on the side near the connecting plate.

[0015] The above technical solution is adopted: threaded grooves are provided on both the connecting plate and the fixing rod, making it convenient to fix the connecting plate and the fixing rod with bolts during use.

[0016] Furthermore, the fixed shaft is slidably connected to the sliding hole in the clamping plate.

[0017] The above technical solution is adopted: by setting a fixed shaft to slide in the sliding hole of the clamping plate, the fixed shaft is avoided from being blocked during use.

[0018] Furthermore, openings are provided on the top of the clamping plate and on the side of the transmission plate near the clamping rod.

[0019] The above technical solution is adopted: by opening slots in the clamping plate and the transmission plate, the clamping rod can slide in them during use, and the clamping rod is prevented from being blocked.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, when the operator operates, the workpiece to be clamped is first placed on the clamping plate, and then the fixing plate is pressed down. The fixing plate drives the transmission plate to slide down inside the clamping plate through the fixing shaft. Since the transmission plate is fixedly connected to the sliding shaft, and the sliding shaft is slidably connected in the inclined groove on the clamping rod, under the limiting guidance of the inclined groove, as the transmission plate moves down, the top of the clamping rod moves downward and abuts against the workpiece. When the transmission plate slides down, it presses down on the end of the transmission rod away from the damper, causing the transmission rod to rotate. Then, through the universal joint, the transmission block slides at the bottom of the clamping plate. The transmission block compresses the damper, and the damper abuts against the series plate and applies pressure to it. When the device encounters vibration, it can quickly absorb and disperse the vibration force through the damper, avoiding the vibration force from acting directly on the clamping rod, minimizing the impact on the clamping rod, and solving the problem of easy detachment of parts in the prior art.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-4As shown, this utility model provides a technical solution: a multi-functional positioning fixture for machining mechanical parts, comprising:

[0031] Clamping plate 1;

[0032] The clamping assembly 2 is placed inside the clamping plate 1. The clamping assembly 2 includes a transmission plate 22 slidably connected inside the clamping plate 1, a clamping rod 21 slidably connected to the transmission plate 22, and a groove provided on the clamping rod 21. A sliding shaft 23 is fixedly connected to the transmission plate 22 and slidably connected to the groove on the clamping rod 21. A transmission rod 29 is slidably connected to the bottom of the transmission plate 22. A transmission block 27 is provided on the transmission rod 29. A universal joint is fixedly connected between the transmission rod 29 and the transmission block 27. A damper 210 is fixedly connected to the transmission block 27. A series plate 212 is slidably connected to the damper 210. A fixing rod 211 is fixedly connected to the series plate 212. A sliding frame 26 is slidably connected to the fixing rod 211. A round block is fixedly connected to the bottom of the clamping plate 1. The fixing rod 211 is slidably connected to the round block at the bottom of the clamping plate 1. The transmission rod 29 is rotatably connected to the clamping plate 1.

[0033] In this invention, when the operator operates, the workpiece to be clamped is first placed on the clamping plate 1, and then the fixing plate 25 is pressed down. The fixing plate 25 drives the transmission plate 22 to slide down within the clamping plate 1 via the fixing shaft 24. Since the transmission plate 22 is fixedly connected to the sliding shaft 23, and the sliding shaft 23 is slidably connected in the inclined groove on the clamping rod 21, under the limiting guidance of the inclined groove, as the transmission plate 22 moves down, the top of the clamping rod 21 moves downward and abuts against the workpiece. When the transmission plate 22 slides down, it presses down on the end of the transmission rod 29 away from the damper 210, so that the transmission... The rod 29 rotates, which in turn moves the transmission block 27 to slide at the bottom of the clamping plate 1 via the universal joint. The transmission block 27 compresses the damper 210, which abuts against the series plate 212 and applies pressure to it. When the device encounters vibration, it can quickly absorb and disperse the vibration force through the damper 210, avoiding the vibration force from acting directly on the clamping rod 21, minimizing the impact on the clamping rod 21, ensuring that small parts are always in a stable clamping state during operation, further improving the processing accuracy, and solving the problem of easy parts falling off in the prior art.

[0034] Furthermore, such as Figures 1 to 4 As shown, the sliding frame 26 is fixedly connected to the bottom of the clamping plate 1. A slot is provided on the circular block at the bottom of the clamping plate 1. The fixing rod 211 is slidably connected in the slot of the circular block. By providing a slot on the circular block, it is convenient to fix the fixing rod 211 through the slot during use, making the connection between the fixing rod 211 and the circular block tighter.

[0035] The clamping plate 1 has an opening at its bottom. The transmission rod 29 is rotatably connected to the bottom of the clamping plate 1 via the rotating shaft 28. When the transmission plate 22 is pressed down during use, it will drive the transmission rod 29 to slide. By having an opening at the bottom of the clamping plate 1, the transmission rod 29 is prevented from being blocked during use.

[0036] A fixed shaft 24 is fixedly connected to the transmission plate 22, and a fixed plate 25 is fixedly connected to the fixed shaft 24. The clamping plate 1 has a sliding hole. By fixing the fixed shaft 24 to the transmission plate 22, when the operator presses the fixed plate 25 down to a suitable position, the bolts on the fixed plate 25 can be used to fix the fixed plate 25, preventing the transmission plate 22 from continuing to slide and thus fixing the transmission plate 22.

[0037] Both the connecting plate 212 and the fixing rod 211 have threaded grooves on the side near the connecting plate 212. By having threaded grooves on both the connecting plate 212 and the fixing rod 211, it is convenient to use bolts to fix the connecting plate 212 and the fixing rod 211 during use.

[0038] The fixed shaft 24 is slidably connected in the sliding hole on the clamping plate 1. By setting the fixed shaft 24 to be slidably connected in the sliding hole on the clamping plate 1, it is avoided to press the fixed shaft 24 against the wall during use.

[0039] The above solution also has the problem that when the clamping rod 21 slides, it will be stuck by the transmission plate 22, such as... Figure 1 as well as Figure 3 As shown, openings are provided on the top of the clamping plate 1 and on the side of the transmission plate 22 near the clamping rod 21. By providing openings on the clamping plate 1 and the transmission plate 22, the clamping rod 21 can slide in them during use, thus preventing the clamping rod 21 from being blocked.

[0040] Working principle: such as Figures 1-4 As shown

[0041] In use, first insert the fixing rod 211 into the sliding frame 26 and the slot on the round block at the bottom of the clamping plate 1, then fix the fixing rod 211 to the processing machinery with bolts, and fix the two ends of the connecting plate 212 to the two fixing rods 211 with bolts.

[0042] Next, the workpiece to be clamped is placed on the clamping plate 1. The operator presses down the fixing plate 25 with external force, causing the fixing plate 25 to drive the transmission plate 22 to slide down in the clamping plate 1 through the fixing shaft 24. This causes the sliding shaft 23 to slide in the inclined groove on the clamping rod 21. Under the limiting action of the inclined groove on the clamping rod 21, the top of the clamping rod 21 moves downward and abuts against the workpiece. After the transmission plate 22 is moved to the appropriate position, the fixing plate 25 is fixed to the clamping plate 1 with bolts, thus completing the clamping of the workpiece.

[0043] During this process, when the transmission plate 22 slides down, it presses down on the end of the transmission rod 29 that is away from the damper 210, causing the transmission rod 29 to rotate. This, in turn, moves the transmission block 27 to slide at the bottom of the clamping plate 1 via the universal joint, causing the transmission block 27 to compress the damper 210. This causes the damper 210 to press against the series plate 212 and apply pressure to it. When the device vibrates, the damper 210 will be used to reduce the vibration force on the clamping rod 21 as much as possible.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
